Let's get this #nakeddiefriday started, people!

The guest of today is one TMS70C42A by TI. It is a 8-bit MCU carrying 4KB of ROM and 256B of RAM, with three timers and a UART.

This particular die was bit by gremlins, and a small part of it is missing; nothing crucial though. Let's have a walk around. 🧵
